Description

technical field [0001] The invention belongs to the field of energy utilization equipment, in particular to a solar thermal energy power system based on an eccentric turbine. Background technique [0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. The development and utilization of energy has greatly promoted the development of the world economy and human society. [0003] However, with the continuous development and consumption of energy, non-renewable energy sources such as petroleum, coal mines, and natural gas are gradually reduced, and energy conservation and recycling are gradually being valued. The basic content of my country's current energy strategy is: adhere to the priority of conservation, based on domestic, diversified development, rely on science and te...

Problems solved by technology

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature requirements for high-temperature heat sources are high, generally above 200°C, and the thermal energy conversion efficiency is low. The thermal energy conversion efficiency is generally 15% to 35%. Under the heat source of ℃, the average thermal energy conversion efficiency is 18%; b. The gasification temperature of the working fluid is unstable, the condensation effect of the working fluid is not good, and the working fluid is easy to deteriorate or appear impurities; c. The driving force of the turbine is small, and the gasification medium The efficiency of converting external work into mechanical energy is low; d. Turbine speed is unstable and prone to stuck problems; e. The heat collection effect of the heat collection device is not good, and the absorption rate of external waste heat is small; f. The heat displacement of the condensing device It is large, wastes a lot of heat energy, and the condensation speed through natural condensation is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; g. The existing equipment is large in size; f. The turbine is prone to leakage Working fluid problem

[0008] In the process of realizing the power output of existing solar energy, the photoelectric effect is first required to convert it into electrical energy, and then output power through electric equipment; at this stage, the equipment used to convert solar energy into electrical energy is mainly a photovoltaic panel. At about 5%, energy waste is serious
